Given a random sample of size 16 from a normally distributed population with a mean of 100 and standard deviation of 24, find P(x bar≤90)
Solutions
Expert Solution
Solution :
Given that,
mean = 
= 100
standard deviation = 
= 24
n = 16
= 100
=
/ 
p (
90
)
P ( -
/)
( 90 - 100 / 6)
P( z
- 10 / 6 )
P ( z
-1.67 )
Using z table
= 0.0475
Probability = 0.0475
